Dolls are the oldest toys, in use since prehistoric times when they were made from materials like clay, fur, and wood. Doll entries are listed by marks printed or incised on the doll, if possible. If there are no marks, the doll is listed by the name of the subject or country or maker. Notice that Barbie is listed under Mattel. G.I. Joe figures are listed in the Toy section. Eskimo dolls are listed in the Eskimo section and Indian dolls are listed in the Indian section. Doll clothes and accessories are listed at the end of this section. The twentieth-century clothes listed here are in mint condition.
